It operates with TypeScript under the AGPL-3.0 license; pick agentflow if agentflow simplifies the creation of complex workflows for large language models through simple JSON configurations. [loonflow](https://github.com/blackholll/loonflow) reports 2.1k GitHub stars, 706 forks, and 20 open issues, last pushed May 25, 2026. [agentflow](https://github.com/simonmesmith/agentflow) has 321 stars, 27 forks, and 13 open issues, last pushed Aug 11, 2023.

See the comparison table for live GitHub stats and shared categories. ### When should I choose loonflow over agentflow? Choose loonflow over agentflow when loonflow is primarily TypeScript; agentflow is Python; License: loonflow is AGPL-3.0, agentflow is MIT; Tags unique to loonflow: devops, django, mcp, ticket; Also covers Developer Tools; You need a fully open-source solution for your internal process automation, as Loonflow requires you to share modifications if used in a SaaS service publically. ### When should I choose agentflow over loonflow? Choose agentflow over loonflow when agentflow is primarily Python; loonflow is TypeScript; License: agentflow is MIT, loonflow is AGPL-3.0; Tags unique to agentflow: json, large-language-models, workflow management; Also covers AI Agents, LLM Frameworks; When you need to rapidly prototype LLM workflows with minimal coding via JSON configs. ### When should I avoid loonflow? You seek closed-source solutions for proprietary reasons as Loonflow's AGPLv3 requirement mandates openness in SaaS settings. When deployment flexibility is essential since the tool relies on Docker for installation, which may not align with all IT environments. ### When should I avoid agentflow? Avoid if requiring advanced customization that goes beyond basic JSON configurations Not suitable for scenarios needing real-time dynamic changes in workflow setup during execution ### Is loonflow or agentflow more popular on GitHub? loonflow has more GitHub stars (2,084 vs 321). Stars measure visibility, not whether either tool fits your constraints. ### Are loonflow and agentflow open source? Yes - both are open-source projects on GitHub (loonflow: AGPL-3.0, agentflow: MIT). ### Where can I find alternatives to loonflow or agentflow? GraphCanon lists graph-backed alternatives at [loonflow alternatives](/tools/blackholll-loonflow/alternatives) and [agentflow alternatives](/tools/simonmesmith-agentflow/alternatives) ([loonflow markdown twin](/tools/blackholll-loonflow/alternatives.md), [agentflow markdown twin](/tools/simonmesmith-agentflow/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/blackholll-loonflow-vs-simonmesmith-agentflow.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, loonflow or agentflow? loonflow: Steady. agentflow: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for loonflow and agentflow? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [loonflow trust report](/tools/blackholll-loonflow/trust); [agentflow trust report](/tools/simonmesmith-agentflow/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=blackholll-loonflow`](/api/graphcanon/graph?tool=blackholll-loonflow) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
